What Does the Flashing Light on My Furnace Mean?
Your heater uses lights to flash code when it is malfunctioning. It also engages this system to let you know it’s working like it should.
Regular operation consists of:
- Concurrent slow flash—furnace working like it should.
- Both lights flash fast—heater is starting to call for heat.
If you realize that a lone light flashing slowly and the other blinking fast, your heater may be experiencing a low flame signal. This can take place even when your furnace is running correctly. It indicates the flame sensing rod could have buildup or in the wrong location on the burner. Reach out to us at 979-335-4262 for assistance.
